Final answer:
The colonization of the Americas in the late fifteenth century led to a global exchange of plant life known as the Columbian Exchange, which had a significant impact on both Europe and the Americas.
Step-by-step explanation:
One effect of the colonization of the Americas in the late fifteenth century was the global exchange of plant life. This exchange of plants and animals between Europe and the Americas, known as the Columbian Exchange, had a profound impact on both continents. European crops such as wheat, rice, and sugarcane were introduced to the Americas, while American crops such as maize, potatoes, and tomatoes were introduced to Europe. This exchange of plant life contributed to the development of new agricultural practices and significantly changed the diets and economies of both regions.
